** connection as that used to execute SQL operations on the virtual table.
**
** All VTable objects that correspond to a single table in a shared
** database schema are initially stored in a linked-list pointed to by
** the Table.pVTable member variable of the corresponding Table object.
** When an sqlite3_prepare() operation is required to access the virtual
** table, it searches the list for the VTable that corresponds to the
** database connection doing the preparing so as to use the correct
** sqlite3_vtab* handle in the compiled query.
**
** When an in-memory Table object is deleted (for example when the
** schema is being reloaded for some reason), the VTable objects are not 
** deleted and the sqlite3_vtab* handles are not xDisconnect()ed 
** immediately. Instead, they are moved from the Table.pVTable list to
** another linked list headed by the sqlite3.pDisconnect member of the
** corresponding sqlite3 structure. They are then deleted/xDisconnected 
** next time a statement is prepared using said sqlite3*. This is done
** to avoid deadlock issues involving multiple sqlite3.mutex mutexes.
** Refer to comments above function sqlite3VtabUnlockList() for an
** explanation as to why it is safe to add an entry to an sqlite3.pDisconnect
** list without holding the corresponding sqlite3.mutex mutex.

** to represent the greater-than-or-equal-to operator in the expression
** tree.
**
** If the expression is an SQL literal (TK_INTEGER, TK_FLOAT, TK_BLOB,

** variable name. Finally, if the expression is an SQL function (TK_FUNCTION),
** then Expr.token contains the name of the function.
**
** Expr.pRight and Expr.pLeft are the left and right subexpressions of a

**
** Expr.x.pList is a list of arguments if the expression is an SQL function,

** the form "<lhs> IN (SELECT ...)". If the EP_xIsSelect bit is set in the
** Expr.flags mask, then Expr.x.pSelect is valid. Otherwise, Expr.x.pList is 
** valid.
**
** An expression of the form ID or ID.ID refers to a column in a table.
** For such expressions, Expr.op is set to TK_COLUMN and Expr.iTable is
** the integer cursor number of a VDBE cursor pointing to that table and
** Expr.iColumn is the column number for the specific column.  If the

**
** If the expression is a subquery then Expr.iColumn holds an integer

** There are three levels:
**
**    OFF       sqlite3OsSync() is never called.  This is the default
**              for temporary and transient files.
**
**    NORMAL    The journal is synced once before writes begin on the
**              database.  This is normally adequate protection, but
**              it is theoretically possible, though very unlikely,
................................................................................
**    FULL      The journal is synced twice before writes begin on the
**              database (with some additional information - the nRec field
**              of the journal header - being written in between the two
**              syncs).  If we assume that writing a
**              single disk sector is atomic, then this mode provides
**              assurance that the journal will not be corrupted to the
**              point of causing damage to the database during rollback.




**
** The above is for a rollback-journal mode.  For WAL mode, OFF continues
** to mean that no syncs ever occur.  NORMAL means that the WAL is synced
** prior to the start of checkpoint and that the database file is synced
** at the conclusion of the checkpoint if the entire content of the WAL
** was written back into the database.  But no sync operations occur for
** an ordinary commit in NORMAL mode with WAL.  FULL means that the WAL
** file is synced following each commit operation, in addition to the
** syncs associated with NORMAL.

**
** Do not confuse synchronous=FULL with SQLITE_SYNC_FULL.  The
** SQLITE_SYNC_FULL macro means to use the MacOSX-style full-fsync
** using fcntl(F_FULLFSYNC).  SQLITE_SYNC_NORMAL means to do an
** ordinary fsync() call.  There is no difference between SQLITE_SYNC_FULL
** and SQLITE_SYNC_NORMAL on platforms other than MacOSX.  But the
